Detailed Description

template<typename Accessor>
struct cds::intrusive::feldman_hashset::hash_accessor< Accessor >

Hash accessor option.

It is most-important feature of FeldmanHashSet. That functor must return a reference to fixed-sized hash value of data node. The return value of that functor specifies the type of hash value.

Example:

typedef uint8_t hash_type[32]; // 256-bit hash type
struct foo {
    hash_type  hash; // 256-bit hash value
    // ... other fields
};

// Hash accessor
struct foo_hash_accessor {
    hash_type const& operator()( foo const& d ) const
    {
        return d.hash;
    }
};
